Application filed June 9,

Be it known that 1 WILLIAM WENDRR- HOLD, a citizen of the ing at New York city, in the county and State of New York, have invented certain new and usefulzlmprovenients in Universal f Projector-Supports, of which the following .jector and lamp house that isa clear, full, and exact description.

The object of this device is to provlde a structural support for a motion picture projustable in all directions.

Another object is to provide the structure I with a power device in such manner that the distance between the driving "and the driven shafts remains constant and unaffected by the adjustments of the support.

Another object is to provide receptacles in the structure that may b used to receive tools, supplies, and carbdlhs may be needed. v Referring to the drawings, l Figure 1' is'a side elevation.

. Fig. 2' is an opposite side elevation.

Fig. 3 is the same. side elevation showing part thereof tilted.

Fig. at is a top view of the device. Fig. 5 is a view of another type of pedestal instead of the four-legged type shown in Figs. 1, 2, 3,4and 6Q artial side elevation of the.

6 is a gged pe estal. c ,As shown in Fig. 1, the legs 1 support the receptacle frame 2, which frame can be lowered or raised on-the legs 1, sincethey are slidably clamped therein by screws 3 (see Fig. 4:). The. frame 2 contains the three" drawers or magazines 4, 5 and ,6, and supports the ivot bracket 7 upon its pivot hub 2? (see 1g.-,6)' which bracket is locked onto frame 2 .in curved slots 8- and 9" by bolts 8 and 9, and 'adjustably clamped ,u on the pivot hub 2 b the bolts 10 and 11. see Figs. 2 and 4). he pivot bracket 7 .su ports the {take-u reel magazine 12, 't e center of the reel supporting shaft .13 being the pivot point of the magazine 12in the bracket 7. A worm sector 14; is fastened to bracket by four screws 15. The worm 16 on shaft 17 is fastened on the magazine 12 by the. bearing brackets 18 and 19.v The worm may be operated by the handle knob 20 and when the desired position of the machine is obtained, the screws 21 will tighten the magazine 12 on the pivot bracket United States, residis easily ad-.

I The clamps 22 and 23 can also be tightened by the bolts 2 and 25-. These clamps are attached to. the magazine 12. On top of the magazine 12 is mounted the projectin head 26. The pulley 27 drives the take-up s aft 13 by means of belt, 28. The pulley 29 drives the mechanism of the projecting head and is driven by means of belt 30, the driving power being derived from the variable speed device 31, as disclosed in my application #165082, filed April 28th 1917, the variable speed device being sup ported by bracket 32, which is fastenedtov the pivot bracket 7 by screws 33, 34 and 35,

and consequently will move with the bracket 7 only. On the bracket 32 is also mounted the electricmotor .36 which drives the speed device 31 by means of coupling 37. The variable speed device is controlledby handle knob 31*; The axis of the driving pulley ,38 on the speed device is in central alinement with the reel support shaft 13, and the pulley 13*, (see Fig. 4) and therefore any tilting of the magazine 12 does not alter the distance between the driving and driven elements 27, 29 and38 and 13, which feature is of great importance and convenience to the operator. The triangular bracket 39 is also securely fastened tothe magazine 12 and supports the lamp ho'using40.

The receptacle frame 2'hav1ng four. legs can be replaced by one support 41, as shown in Fig. 5, being also provided with receptacles 42and 4:3 in. bracket 44 which can be revolved around the pivot point 41 Considerable changes can be made in the structure without departing from the prin-- ciple of providing adjustment, in alldirections without altering the distance between the motive power and the driven elements and providing the structure with receptacles of usefulness as herein described. 'WhatI-claim as my invention is:

I 1. A supporting structurefor a projecting apparatus consisting of a main base, a sec:

ond'base pivotally supported thereon upon a vertical axis, magazines or drawers vinthe main base, a source of power supported by the second base, a film reel magazine pivotally mounted upon said second base, a horizontally disposed reel shaft for actuating said reel magazine, said reel shaft forming the pivotal axis for said reel magazine, said shaft being disposed in longitudinal alinement with the driving element of the driving (Au-I power source, means to pivotally adjust said second base and said reel magazine, and a projecting apparatus Supported bysaid reel magazine.

2. A supporting structure 'of a projecting apparatus comprising a main base having legs, a second base pivotally mounted upon a vertical axis on said main base, a horizontally disposed film reel supporting shaft mounted in said second-base, a film magazine pivotally supported on said shaft, a motor also carried by said second, base, a driving element connected to said motor and arranged in longitudinal alinement with the filmreel supporting shaft, and means to rotatively adjustsaid film magazine about its horizontally disposed supporting shaft, and meansfor adjusting said second base about its vertically pivotal axis.

3.. A supporting structure for a projecting apparatus consisting of a main base, a member mounted thereon foraxial movement on a vertical mas, and means for ad ustlng said member about said axis, a horizontally disposed shaft mounted in said member, a reelmagazine pivotally mounted upon said shaft, a worm gear connected to said magazine, means engaging said worm gear to rotatively adjust said magazine upon its supporting shaft, a projecting apparatus carriedby said magazine; a motor mounted on said first-named member, the driving ele as J messes ment of said motor being arranged in line with the horizontally disposed reel magazine supporting shaft, and means to transmit power from said motor to the projecting apparatus. 7

4. The herein described device for supporting a projecting apparatus, consisting of a rigid base having magazines, an upright member pivotally mounted on said base, a source of power, a bracket on said base and forming a support for said source of power, a projector, a pivotally mounted film reel magazine arranged to support said projector, and means to adjust said maga- 5. In a supporting structure for projection apparatus, the combination of a main supporting base, a secondary base adjustably mounted upon said mainbase, a horizontally disposed film reel supporting shaft mounted upon said second base, a film magazine pivotally supported on said shaft, a motor carried by said second base, a driving element connected to said motor, and mounted in alinement with the film reel supporting shaft, and means to rotatively adjust said film magazine on its horizontally disposed supporting shaft. &
